So it goes like this:
“Sally, you look groovy. You aim to win at the best DRESS competition tonight, don’t you?”
"Sally, you look groovy. You aim to win at the best DRESSED competition tonight, don’t you?”
I've heard people say best dress cannot be used in the context of boys because they do not wear "dresses". But what if the context if a girl? Is one sentence more grammatically correct than another?
